D. c. BAILEY WINDOW GLASS GUID Filed July 30, 1935 Patented Sept. 29, 1936 UNITED STATES PATENT OFFICE Application July 30,

15 Claims.

This invention relates to that type of window glass guides, which are usually employed in automobile bodies, which are so constructed that they may be readily bent by hand to conform to curved window frames.

While guides of this character which have been produced are suiiiciently satisfactory in many respects, there is a constant demand for reduced cost of production, and as the cost of materials generally considerably exceeds the cost of labor, a substantial saving in the cost of materials, even though it may rsult in some increase in the labor cost, is often desirable.

The primary object of my invention is to produce a guide of the above described character in the production of which a substantial saving in the cost of materials may be made without increasing the cost of the labor item to an objectionable extent, and which will otherwise be as satisfactory as guides of this character which have previously been produced.

I accomplish this object primarily by providing a core, on which suitable cushioning material may be mounted, and which primarily consists of a strip of sheet metal, the middle portion of which has been cut so as to separate the strip into two sections each of which comprises a continuous portion forming an edge of the core and a series of tongues, extending from said continuous portion, the end portions of said tongues being lapped to form the bottom of the core.

For a more complete disclosure of my invention, including several forms thereof, reference is made to the following specication in connection with the accompanying drawing in which:

Fig. 1 is a view in side elevation showing an embodiment of my invention installed in a Window casing.

The form of my invention shown in Fig. 2 may be best described by an explanation, in a general way, of the manner in which'it is constructed. A strip of thin sheet metal, having parallel edges,

1935, Serial No. 33,851

is cut or punched in a zig-zag line along the middle thereof, as shown in Fig. 4, dividing the strip into two sections, which comprise continuous edge portions I4, I5, from which a series of equally spaced tongues I6, I1, extend in perpendicular relation, said tongues being, in this instance, straight and having square ends. Said sections are then partly separated laterally, so that the tongues of each section still lie edge to edge in the same alternate positions, with their end portions lapped, as shown in Fig. 5. Each edge portion is then wrapped about a reinforcing Wire I8 and I9, and the end portions I6', I1 of the tongues are bent reversely to an extent, also as shown in Fig. 5.

A strip 20 of cushioning material such as felt, or a textile material having a heavy nap, is provided, of a Width corresponding to the width of the bottom of the channel to be formed, the edge portions of the strip having slits 2| formed at intervals therein, as shown in Fig. 8.

Said strip 20 is then placed on the portions of the tongues which lap each other and the end portions I6', I1 of the tongues are thenbent about the edge portions of the strip, so that the strip is firmly clamped thereby at each edge, as shown in Figs. 2 and 3, thereby securely connecting said cushioning strip to the core sections, and, as the strip has substantial stability, relative movement of the sections will be prevented.

In the present instance metallic iinished edges or ornamental beads for the edges of the channel are not desired, and a cushioning side and edge covering of felt, or textile material with a heavy nap, is provided. A strip of the material employed for this purpose is separated into two sections by a zig-zag cut similar to that employed in forming the core sections, said cushioning sections thereby comprising continuous edge portions 22, 23 from which tongues 24, 25 extend. The edge portions 22, 23 are Wrapped about the wire reinforced edges of the core sections, so that they extend onto what is 'to be the inner side of the channel to a suiiicient extent to provide a suitable cushion for the sides of the glass, and then about the opposite side across the middle portion, so that the tongues 24, 25 lie against the tongues I6, I1 respectively of the core and extend thereon to the reversely bent end portions I6', I'I' thereof. 'I'he edge portions 22, 23 of said cushioning sections which are wrapped about the edges of the core may be secured by any suitable means, as by stitches 26 which pass through the spaces between the` tongues adjacent the edge portions and the remaining portions of said cushioning sections may be secured to the tongues of the core sections by a suitable cement.

The parts as thus arranged are then bent into channel form, the reversely bent ends of the tongues which are clamped to the bottom cushion 20 being located at the vertex of the angle between the bottom and each side, as shown in Fig. 2.

The slits 2l in the bottom cushion 2U are spaced apart to correspond to the distance between the tongues I6, l1, and, when the cushion is placed in position, care is taken so to locate the strip that the slits 2l therein at each side are approximately mid-way between the tongues which extend from the section at the side of the channel next the edge, as shown in Fig. 3, so that the slits are located mid-way between the portions which are grasped by the tongues extending from the opposite core section. Consequently, when the channel is bent to conform to a curved window frame, as shown in Fig. 1, the tongues l5, I1 will be swung away from each other to a slight extent, and, as the tongues grasp the strip at their ends, the slits will be slightly opened by this movement of the tongues. This bending movement also tends to stretch the bottom strip, and the slits 2| therein assist in permitting this stretching action, which, for any particular portion, is slight. Also each section of covering material on the outer side of the channel only extends over the tongues of the section to which it is directly attached, so that this material does not obstruct the bending operation, and as the continuous portions of the channel are at the edges of the sides and are very narrow, they may be readily bent and do not interfere with the bending operation to an appreciable extent.

The bending operation may therefore be readily performed.

As in use the channel is tted into a groove of the window casing, there is no possibility that the sections of the channel will become relatively displaced after it is inserted, and the bottom strip 20 has suilicient stability to hold the sections in place up to the time of insertion.

It will be noted that a substantial saving of metal for the core is thus made, as the width of the strip, of which it is formed, is substantially less than the sum of the widths of the two sides and bottom of the channel.

When an external covering of thin textile material is employed, the construction is slightly modified, as shown in Fig. 9. In this instance each tongue is bent to provide an intermediate curved portion as 16a, which registers with the reversely curved portion of the adjacent tongues, so that the bottom of the channel at its corners is not indented. In this form a textile covering 21 is extended entirely about the outer sides and bottom of the channel and is clamped by the edges of the core sections, and cushioning strips 28 are arranged on the sides for engagement with the glass, and are secured in like manner.l

The bottom cushion 29 is clamped by the ends of the tongues as previously described.

Another form of my invention is shown in Fig. 10, in the production of which the strip from which the metal core sections are formed are cut in oblique directions to the edge portions, as shown in Fig. l1, forming two sections having continuous edge portions 30, 3l, from which tongues 32, 33 extend in parallel relation, butI atan oblique angle to the edges. The edge portions are then reinforced with wires 34, as in the previously described construction, and the sections are completely separated and their positions are reversed relatively, and then they are placed together, as shown in Fig. 12, so that the tongues overlap each other alternately, one

tongue of one section being passed over two of the first section being passed beneath the two succeeding tongues of the other section, and so on. The sections as thus arranged are then covered with rubber 35 on both sides, preferably by an extruding process, and then they are bent into channel form.

In this instance a cushioning strip 36 is cemented to the bottom of the channel and side cushioning strips 31 are secured on the inner sides by cement and by metal edge beads 38, these parts usually being applied before the core is bent into channel form.

When the channel, as thus constructed, is bent to conform to a window frame, the rubber coating between the tongues will yield suiciently to permit the tongues to be swung apart to the slight extent necessary and the bottom cushion will be stretched sufficiently to permit this action and may be slitted, as illustrated in Fig. 8, to facilitate this action.

In this form of my invention a substantial saving in metal of which the core is formed will be made in like manner to that already described with relation to the other constructions and, as the tongues are interwoven, a core is formed which will be suiciently substantial for the purpose.
